Introduction: Electrospun nanofibers are suitable option to synthesize filtering mats for nanoparticles. This study was aimed to fabricate polyurethane nanofiber mats through electrospinning process and to investigate the effect of different parameters such as packing density, face velocity and particle type on the filtration efficiency and quality factor of electrospun polyurethane nanofiber m...
Palm oil mill effluent (POME) poses a great threat to the environment. However, it contains valuable resources such as energy, water and nutrients that could be recovered for sustainable development. Currently, anaerobic digester has been employed to recover the energy potential in POME. However, the presence of suspended solids in the digestate hinders the downstream nutrients recovery process...
در پژوهش حاضر، سه گونه باکتریایی بیمارگر erwinia carotovora، xanthomonas axonopodis و streptomyces turgidiscabies به منظور یافتن پکتیناز خارج سلولی که توانایی شکست پکتین مرکبات با درجه استریفیه بالا را دارد، مورد بررسی قرار گرفت. در این میان، گونه xanthomonas axonopodis دارای بهترین فعالیت پکتینازی می باشد. بهینه سازی شرایط کشت نشان داد که این باکتری در محیط حاوی1/0% پکتین مرکبات، 1% پپتن، 1%ye...
